time Ijroadly impressed. Abdomen rather thinly cinereo-puljesceut, the legs 

 decidedly thick. Length 1.7-2.6 mm. ; width 0.8-1.15 mm. 



California (San Diego). Mr. Dunn. 



The female difter.s from the above descrilied male in its larger 

 size, relativel}" longer and wider elj'tra, smaller head, more slender 

 a nd less claviform anterior tibire and especialh^ in its much 

 shorter and more slender antennae, with the fifth joint distinctl}^ 

 dilated and very transverse, the sixth and eighth being small; 

 also in the smoother sculpture of the pronotum. The fifth ven- 

 tral of the male is verv short and transversel}' truncate. 



This species, which was taken in some abundance, is evidently 

 allied to hrevicornis, but may be distinguished b}' the sparser 

 vestiture, less transverse prothorax which is more evenh'^ 

 rounded at the sides, and bv slight differences in the antennal 

 structure of the female. 



53. T. iiisigiii«i n. sp. — Oblong, stout and convex, polished, hlack:legs 

 and antenna; black with the funicle of the latter slightly pale toward ])ase, 

 and the tarsi piceous; pubescence rather long, dense and decumbent, pale 

 luteo-cinereous, becoming blackish in a discal spot on each elytron near the 

 base and another much larger behind the middle; body bristling throughout 

 with long erect black seta\ Head scarcely more than one-half as wide as the 

 prothorax, smooth, finely but strongly and sparsely punctate, the impressions 

 very feeble; epistoma long, truncate; labrum long, strongly rounded at apex; 

 eyes rather large, nearly attaining the base; antennic somewhat slender and 

 scarcely at all incrassate, a little longer than the prothorax, the outer joints 

 not asymmetric and but feebly transverse, fifth only slightly dilated. Pro- 

 thorax three-fifths wider than long, widest slightly behind the middle where 

 the sides are very broadly and obtusely subangulate, thence just visibly con- 

 vergent and straight to the basal angles which are nearly right and but slightly 

 blunt, more convergent and straight to the apical angles which are but slightly 

 blunt and somewhat prominent anteriorly from above; apex distinctly nar- 

 rower than the base, both transversely truncate; disk finely, sparsely punctate 

 and highly xiolished, not at all rugose laterally. Elyira one-half longer than 

 wide, only slightly wider than the prothorax, parallel and straight at the 

 sides, evenly but rather broadly rounded at apex, the punctures fine but 

 strong and rather close-set. Abdomen very minutely and densely punctu- 

 late, densely clothed, as are also the legs, with luteo-cinereous pubescence. 

 Length 3.6-4.0 mm. ; width 1.6-1.8 mm. 



California (southeastern). 



The two representatives of this striking species before me are 

 both females, and the second specimen has the two large dark 

 spots on each elytron subconfluent, the posterior pair uniting also 

 transversely on the suture.
